CULTIVATOR ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 773,993, dated November 1, 1904.

Application filed July 21, 1904. Serial No, 217,507. (No model.)

To mZZ whom it may concern:

Be it known that I, J ACOB A. SCHOWALTER, acitizen of the United States, residing at Halstead, in the county of Harvey and State of Kansas, have invented certain new and useful Improvements in Cultivator Attachments; and I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in frames for cultivators; and the object of the invention is to produce an archframe made up of sections, one of said sections being provided with an arm pivotally connected thereto and adapted to be held in an adjusted position through a loop upon the other section of the arch by means of pins against which one of the sections of the frame is adapted to contacttolimit'the throw, thereby providing means for easily and quickly adjusting a cultivator to different widths of rows to be cultivated.

The invention consists, further, in various details of construction and in combinationsand arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which- Figure 1 is a perspective view of my improved cultivator-frame, and Fig. 2 is an enlarged detail view of the pivotal arch-sections.

Reference now being had to the details of the drawings by letter, A and A designate, respectively, the two beams of a cultivator hav ing the cultivator-plows B, which are adjustably held upon the beams by means of thumbscrews a a. To the rear end of the beam A is secured a plate A and to the rear end of the beam A is secured a bar or plate A C and C designate, respectively, two arched sections of the frame, the lower ends of which are fixed to the angle-irons N, fastened to said beams. The upper ends of said arched sections are pivoted together at O and said section C is provided with a strap E for the reception of an apertured and curved bar D, which is pivoted at D to the section C. Said bar has a series of perforations cl therein and is provided with a pin cl, which is adapted to be inserted in one or another of the apertures (Z and against which the inner edge of the arch-section C is adapted to contact to limit its throw toward the section 0, while a pin 0 is adapted to be positioned in one or another of the apertures near the free end of said bar to prevent the outer throw of the section C.

From the foregoing, when taken in connection with the drawings, it will be observed that by the provision of my sectional archframe means is provided which may be applied to various makes of cultivators and so constructed that the beams may be readily adjusted, so that the cultivator-plows will operate in rows near together or farther apart, accordingly as the apertured bar may be adjusted by means of the pins.

While I have shown a particular detailed construction of adjustable arch-frame for cultivators, it will be understood that I may vary the detailed construction, if desired, without in any Way departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with the beams A having angle-irons arranged in pairs and spaced apart and fastened to the upper surfaces of said beams, the arch members, pins carried by said angle-irons and passing through the lower ends of said arch members, the upper ends of the arch members being pivoted together, a curved bar pivotally connected to one of the arch members, a curved strap fitted to the opposite arch member and between which and the member to which it is secured, said bar is adapted to have a play, and a pin carried by the curved bar adapted to contact with the edge of one of said arch members, as set forth.

In testimony whereof I hereunto afiiX my signature in presence of two witnesses.
